DXA: Bone Densiometry

DXA: Bone Densitometry

Osteoporosis Screening

DXA stands for dual-energy X-ray absorptiometry. This procedure is used
to detect osteoporosis via a very low dose of X-ray energy. Beginning
in peoples' mid-thirties, bone mineral content begins declining and
in post-menopausal women it accelerates. DXA makes it possible to detect
the early stages of bone density loss and enables earlier treatment. Osteoporosis
is a potentially debilitating condition which can lead to more vulnerability
for bone fractures, decreased mobility and independence.

What to Expect

You'll lie on a table and the exam arm will pass over your body. The
only preparation needed is to avoid calcium supplements for 48 hours before
your appointment. Also, if you've had any kind of barium study you'll
need to wait at least 14 days between tests to avoid barium interference
with the DXA exam. A DXA scan is an easy procedure for the patient and
takes about 15-30 minutes. Be sure to wear comfortable, metal-free clothing.
